【摘要】 十屋断陷源岩分布的不均一性、复杂性，以及多期构造活动使源岩类型、演化程度的不均一性，是造成不同成熟度石油、油型气、煤型气有规律分布的主因。纵向上多套储盖红合，多类型、多期次圈闭为油气富集提供了多层次的场所。断层和不整合面的垂向和侧向输导作用，构成油气运移富集的空间网络。油气成藏的关键时期为嫩江期末，关键因素为圈闭形成期与油气生、运、聚的配置。在此基础上，总结出两种类型（油型、煤型），两个期次（早期、晚期），三种方式（跨越式、近源式、混源式）的油气成藏规律和六种成藏模式。更多还原

【Abstract】 The heterogeneity, the complexity of source rock distribution, the heterogeneity of source rock types and evolution that resulted from multi--stage tectonic actions in Shiwu Fault--Depression are the main factors causing oil,oil--type gas and coal-gas to distribute regulaly. Multi-series of reservoir--cap assemblages and multi--stage trapping provide multi layer reservoir spaces for oil and gas enrichment; faults and unconformity surfaces are passages for hydrocarbon migration and acCumulation. The key period in forming hydrocarbon pools was Nenjiang stage and the key factor was the matching of trap formation period with hydrocarbon generation, migration and accumulation period. According to above mentioned, two hydrocarbon pool forming types, three pool forming ways and six pool forming models have been concluded.更多还原
